SPIKE-FULLER.

SPECIFICATION forming part of Letters Patent No. 622,150, dated March 28, 1899.

Application iiled September 6, 1898. Serial N0. 690,346. (No model.)

To all whom, t may concern.-

Be it known that I, JOHNA. HOPEWELL, of Arnprior, in the county of Renfrew, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Spike-Fullers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part thereof.

My 'invention, which will be hereinafter fully set forth and claimed, relates to devices for extracting spikes.

The object of myinvention is a spike-puller of simple and eective construction by which a spike of any description may be extracted from wood without bending it, and therefore without enlarging the spike-hole or damaging the wood or spike.

Figure l is a front vieW'of my improved spike-puller. Fig. 2 is a side View of the same. Fig. 3 is a view of the stand of the same stripped of all its attachments; and Fig.

4 is a transverse section of the same on line 4 4, Figs. l, 2, and 3, on a somewhat larger scale.

A is a portable stand conveniently formed of a vertical front plate and two ribs at the back, the outer edges of the front plate and ribs tapering toward the upper end, leaving the front face vertical. Asomewhat enlarged or broadened plate at the lower end forms a foot a. The top of the front plate is slotted at a right angle to the face to form a forked head ct', with a couple of transverse eyes 4 in the ribs to receive a pivot pin or bolt. A vertical slot 2 is also provided in the front plate immediately above the foot at a vright angle to the face, and the foot enlargement is cut away at 3 in the center of the front to leave a clear vertical face. In the slotted head ct is pivoted ahand-leverB upon a bolt or pin b, passing through one of the eyes 4. To the front end of said lever is pivoted a depending link-plate C, parallel to the face of the stand and slotted at the top to receive the eyed end of the lever B, through which passes the pivot pin or bolt c, held in the transve-rsely-eyed upper end of said plate.

D l) are a pair of curved crossed shearbars, pivoted at their upper ends by short links E E to the plate C, their lower ends reinforced and provided with beveled bitinggrips d to engage the spike. A short transverse plate or bar F is held slidingly by a boltf passing through the slot 2 in the stand and being secured at the rear of the front plate. To this bar are pivoted the shearbars by pins f', passing through said bar near its ends and through the shear-bars, and a similar plate or bar F on the outer face of the latter.

It will be observed that if the handle end of the lever B is raised the link-plate C is lowered, allowing the shear-bars D to drop also, thebolt fof the bar F sliding in the slot 2. A continued movement of the lever B in the same direction after the grip ends of the shear-bars have found a support will separate the upper and also the lower ends of the latter-71. e., spread them farther apart. When the grips have been set upon the spike, the handle end of the lever B is depressed, the ends of the shear-bars approach each other as far as the thickness of the spike between the grips at their lower ends will allow, and when this lateral movement of the shear-bars has been stopped and the grips are biting the spike they must follow the upward movement of the link-plate G,i1npelled by the lever B, the bolt f sliding upward in the slot 2, and the spike is being extracted.

I claim as niy invention- 1. In a spike-puller, the combination of a stand with foot having a vertical face, a lever pivoted in the upper end of said stand, a link-plate pivoted to the end of said lever near the face of said stand and parallel thereto, a pair of shear-bars having grips at their lower ends, links pivotally connecting said shear-bars with the link-plate and a crossbar secured slidingly to the lower part of said stand to which each of said shear-bars is pivoted, substantially as set forth.

2. In a spike-puller, the combination of a portable stand having a slotted head and provided with a vertical slot near the foot, a cross-bar with bolt secured to said stand and sliding in-said slot, a lever pivoted in the slotted head, a link-plate pivoted to the short end of said lever, shear-bars having bitinggrips at their lower ends and pivoted to said IOO cross-bar and links pivotztlly connecting the cured slidingly to said stand and to which upper ends of said shear-bars to the linkeach shear-bar is pivoted, substantially as plate, substantially as set forth. set forth.
